The fundamental ingredients required to deliver BIM Level 2 – a portfolio of standards and tools that will help drive your BIM implementation strategy.

You can find more information (and download full versions of the documents referenced) on the BIM Level 2 website , launched earlier this year to become a one-stop-shop when it comes to standards, tools and guidance on meeting the requirement.

The key ingredients for BIM implementation success

PAS 1192-2:2013
Specification for information management for the capital/delivery phase of construction projects using building information modelling

PAS 1192-2 has its origins in BS 1192-2007 but introduces new concepts including an employer’s expression of information they require from a project and the appropriate format for this information (Employer’s Information Requirements or EIR), and BIM Execution Plans (BEPs) – showing how the supply chain will meet the requirements of the EIR.

PAS 1192-3:2014
Specification for information management for the operational phase of assets using building information modelling

Building on previous 1192 publications, PAS 1192-2 develops these for use across the operational life of assets. Key concepts include:

Organisational Informaiton Requirements (OIR) – the information an organisation needs to run the business

Asset Infomation Reqirments (AIR) – the information the organisation needs about the asset it is responsible for

Asset Information Model (AIM) – the information or dataset used to describe an asset

PAS 1192-3 sets out the need for comprehensive and accurate information and establishes the AIM which can be used as the basis of all asset-related decision-making. This makes it of particular importance when it comes to establishing requirements for facilities managers down the line. Given the reliance on the AIM it is vital that this is kept up-to-date and accurate throughout the project.

Collaborative project require information to be exchanged. PAS 1192-4 codifies expectations on what information is exchanged throughout the lifecycle of an asset. It also establishes requirements for reviewing and checking for compliance, continuity and completeness. COBie is the UK Government’s chosen information exchange schema for federated BIM Level 2, alongside graphical BIM models and .pdf documents.

PAS 1192-5 explores security requirements for BIM and digital built-environments and the steps required to create and cultivate an appropriate security mindset and secure culture within an organization, including the need to monitor and audit compliance. It does this by outlining cyber-security vulnerabilities and codifying an assessment process to determine appropriate levels of security for BIM collaboration.

The approach outlined in this PAS is applicable not only to projects employing BIM and the implementation and use of smart asset management, but to any built asset where asset information is created, stored, processed and viewed in digital form. It can also be applied to situations where digital survey data is captured as part of asset management or in readiness for a future project.

BS 8536-1:2015
Building for design and construction. Code of practice for facilities management (Buildings infrastructure)

BS 8536-1 aims to ensure that designers consider the expected performance of a building in use (whether new-build or refurb). It does this by involving the operator, operations team and supply chain from the outset and extending the supply chain’s involvement through to operational and after care phases. It includes briefing requirements for soft landings, BIM and post-occupancy evaluation.

BS 1192 sets out a ‘best practice’ method for developing, organising and managing production information for the construction industry by way of a disciplined collaborative process and naming schema. It provides a template for common naming conventions and approaches to collaborative working and efficient use of date in facilities management.

Building Information Model (BIM) Protocol

The BIM Protocol was published by the Construction Industry Council (CIC) in 2013 and acts as a supplementary legal agreement that can be easily incorporated into professional services appointments and construction contracts by way of a simple amendment. It identifies building information models that are required to be produced by the project team and puts in place specific obligations, liabilities and associated limitations on the use of those models. The protocol can also be used by clients to require the adoption of particular ways of working – adopting a common naming standard, for example.

Government Soft Landings (GSL) powered by BIM

GSL is a form of gradual handover for new and refurbished buildings, where the project team is contracted to watch over the building, support the occupant and to fine-tune the building’s systems, for up to three years post-completion. The link with a (Government) Soft Landings process may initially seem tenuous, but it is vital that the way the asset is used and maintained is considered during the briefing and design process to ensure best value is achieved in the operational lifecycle of an asset. The data gathered during the operational phase of an asset can be very important in helping to shape project needs through effective Employers Information Requirements (EIRs).

Digital Plan of Work (DPoW)

At each stage of a construction project there will be a series of deliverables.The digital plan of work allows an employer to define the deliverables required at each stage – from design and construction, through the maintenance and operation phases. As more information becomes known at each stage, the level of detail will increase as more information is added and shared. The digital plan of work codifies who must deliver what information and when. NBS created the NBS BIM Toolkit to allow this information to be captured and shared across project teams in accordance with the digital project lifecycle defined in PAS 1192-2.

Uniclass 2015

Uniclass 2015 is a standardised classification system for the UK construction industry covering all sectors and integrates with the digital plan of work. It exists to ensure that data is able to be indexed and structured to make it easily accessible in a common format.

It contains consistent tables classifying items of all scale from a facility such as a railway down through to products such as a CCTV camera in a railway station.

This new classification system was a key deliverable of the Innovate UK funded BIM Toolkit project. As part of this project, NBS worked with experts from across the industry to develop Uniclass 2015. This builds on previous versions and developments of Uniclass by CPI, but significantly extends the scope and responds to industry feedback to this previous work.
